CABLE-GRIP.

Specification of Letters Patent.

Patented ]Dec. 2 1913.

Application filed December 7, 1912. Serial N 0. 735,360.

' To all whom it may concern:

Be it known that we, WILLIAM JOHNSON PARKER and ABRAHAM ANDRES SrRoM,subjects of the King of Great Brltaln, residing at I-Ialifax,'in theProvince of Nova Scotia,

Canada, have invented certain new and us ful Improvements inCable-Grips, of which the following is a specification.

The present invention relates to certain new and useful improvements inwire or cable grips such as are adapted to be em ployed forstretchingcables or the like.

One of the objects of the invention is to provide a cable grip which iscompact in its construction, which comprises few and durable parts, andwhich .will tightly and firmly grip a cable and will not injure aninsulating wire or cause kinking of the wire.

While the cable grip may be employed wherever such a grip is desired,yet it is more particularly designed for use in the laying of deep seacables, where it is very important that the grip be positive andreliable in its action so as to prevent slipping of the cable at aninopportune time, or injury to the cable.

With. these and other objects in view, the invention consists in certainnovel combinations and arrangements of the parts as will more fullyappear as the description proceeds, the novel features thereof beingpointedout in the appended claims.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawing, in which Figure 1 is aside elevation of a cable grip clamp constructed in accordance with theinvention. Fig. 2 is a transverse sectional view on the line 22 ofFig. 1. Fig. 3 is a similar view on the line 3.3 of Fig. 1. Fig. 4 is abottom plan view of the upper clamp member. Fig. 5 is a side elevationof the lower clamp member.

Corresponding and like parts are referred to in the following descriptioand indicated in all the views of the drawings by the same referencecharacters.

Specifically describing one embodiment of the invention, the numeral 1designates the base or body portion of the stock, the said stock beingformed in complemental sections which produce a converging guidewaywithin which the tapered or wedge shaped jawis mounted. The'base 1 is ofan elongated formation and is provided at the rear end thereof with aneye 2 by means of which the device can be secured to any suitablestationary support. The upper face of the base 1 is provided with alongitudinal groove or guideway 3 which extends the entire lengththereof and forms a seat upon which the jaw 4 is slidably mounted.'Projecting upwardly from the base 1 upon opposite sides of the guideway3 are a pair of flanges 5, the said flanges being arranged atthe forwardend of the base and only extending from said end to about the middle ofthe base. Each of these flanges is provided upon the outer side thereofwith a longitudinal groove 6, the said grooves being located immediatelyabove the top of the base 1 and extending from the rear ends of theflanges 5 to a point spaced from the forward ends of the flanges wherethey terminate in the shoulders 7.

The upper and complemental section 8 of the stockisremovably fittedagainst the upper face of the base 1 and is constructed to have adetachable and interlocking connection with the flanges 5. This uppersection 8 is formed with a tapered groove or seat 9 which has an opposedrelation to the seat 3 of the base 1 and receives the wedge shaped jaw10. This detachable stock member 8 is considerably shorter than the base1, the total length thereof being substantially equal to the length ofthe flanges 5. The sides 8 of the removable member 8 fit upon theexterior of the flanges 7 andv are provided with the ribs 11 which areadapted to enter the grooves 6 of the flanges 5. i

When applying the detachable member 8 to the base 1, it is first fittedagainst the rear end of the base 1 with the ribs 11 in alinement wit-hthe grooves'fi, and then slid forwardly upon the base so that the ribs11 are received within the slots 6. These ribs 11 abut against theshoulder 7 when the detachable section 8 has reached its operativeposition, with the nose or forward end thereof flush with the forwardend of the base 1. In order to detach the removable section 8 from thebase 1, the above operation is reversed.

The wedge shaped jaw 4 slides freely upon the base 1 while the jaw 10has a wedge shaped formation and is designed to cooperate with theinclined face of the seat 9 of the removable member to force the jawstogether. and cause them to gripa wire or cable inserted between thejaws. The forward ends of the jaws4c and 10 are pro:

vided with the respective rounded portions ."01 enlargements 4 and 10which are designed to be tapped upon with a hammer or other tool for thepurpose of forcing the member 8 of the stock, the said member 8 and base1 are connected by a'chain 12, the ends of the chain engaging suitableears 13 upon the respective members. This chain is of position andcable,

such a length as to admit of the members being readily detached fromeach otherwhen desirable. It will also be noted that the wedge shapedjaw 10 is provided with a groove 14 for receiving the end of a pin 15upon the removable member 8, the said pin serving to. retain the wedgeshaped jaw in to engage the ends of the slot to limit the slidingmovement of the wedge shaped jaw. The greater the pull upon the the.moretightly the jaws t and 10 will gripthe same, formation-ofv the jaw 10cooperates with: the inclined base of the seat 9 to force the jawstightly together when any pull is exerted upon the same. In order torelease the jaws, the enlarged forward ends 4? and 10 thereof may belightly tapped with a hammer or other suitable implement, therebyloosening the same. I Having thus what we claim as new and desire tosecure by Letters Patent, is

1. A cable grip including a base formed with a seat and provided uponopposite sides of the seat with flanges, said flanges being ablygripping faces being since the wedge shaped described the invention,

rheonva formed with longitudinal grooves which terminate at, one endthereof in shoulders, a removablemember formed with an opposed seat andwith" sides adapted to slidengagethe before mentioned flanges, the saidsides being provided with ribs adapted to enter the longitudinal groovesof the flanges and engage the shoulders at the ends thereof to limit thesliding movement ofthe removable member and retain the same in position,the seats, of the two members converging toward each other, andcooperating jaws slidably mounted upon the seats, one of the said jawshaving a wedge shaped formation.

2. A cable grip including-a base provided with a seat and formed withside flanges on opposite sides of the seat, the said side flangesextending from one end of the baseto an intermediate point in the lengththereof and being provided. with longitudinal grooves which extendinwardly through the rear engs of the side flanges and terminate inshoulde s, a removable stock member which is shorter than the base andis provided with a seat and'wi'th sides which embrace and 'slidablyengage the before mentioned flanges, the said sides being provided withlongitudinal ribs which are adapted to enter the grooves of the flangesfrom the rear thereof and engage the shoulders at the forward endsthereof to -limit the forward sliding movementv of the removable stockmember and hold the same in position, the seats of the two membershaving a converging relation, and a pair of cooperating jaws. slidablymounted between the converging seats, one of the jaws having a wedgeshaped formation.

In testimony whereotwe aflix our signatures in presence of twowitnesses.
